CurveBeam’s Volunteer Day Warms Community

The holiday season is an excellent time for any company to celebrate and share its values. The team at CurveBeam believes in giving back, just as much as it believes in innovation. To reach out with this spirit, a group of CurveBeam volunteers recently connected with an amazing organization.

Everyone had a simple goal in mind: to make sure kids in the community have the supplies they need for this season and beyond.

Cradles to Crayons serves as a resource for communities in need and a hub of civic engagement in Greater Philadelphia. This organization provides children from birth through age 12 living in homeless or low-income situations with the essential items they need to thrive – at home, at school and at play – free of charge.

Ensuring kids are safe, warm and ready to learn throughout the year

Cradles to Crayons was founded in 2002 to get basic necessities to the kids who need them, including clothing, school supplies, toys, and more. The organization provides all the physical goods that children need to be safe, protected from the elements, and ready to learn.234585951194320-834hbvhp2y7forv0xdvp_height640

By supplying kids with high-quality used or new goods, Cradles to Crayons and its partners make children feel valued.

The organization partners with social service organizations to connect groups that have surplus resources with the communities and families that need them. Cradles to Crayons makes it simple for children, families, and corporations to participate by organizing a clothing collection, hosting a fundraiser, or working in one of its warehouses.

Charity Navigator – an independent group that rates charities on both their organization capacity and efficiency – recently awarded the Cradles to Crayons a four-star rating: their highest ranking. In receiving this designation, Cradles to Crayons was recognized for exceeding industry standards and outperforming most charities in its cause.

In addition, Cradles to Crayons Philadelphia was included in Main Line Today‘s list of local charities to support.

A CurveBeam volunteer party

In lieu of a traditional Christmas party, a group of CurveBeam volunteers spent half a day at Cradles to Crayons, helping prepare items to go out to kids in need in time for the holidays.

The team enjoyed the experience. It was the perfect expression of the company’s ongoing commitment to giving back, and one the team looks forward to repeating next year.

Curvebeam at RSNA 2016

In November many of the greatest minds and innovators in radiology convened in Chicago for the 2016 RSNA. We had our talented and skilled team representing us and our innovations. While there we unveiled the prototype for the LineUP, a bilateral weight-bearing Cone Beam CT imaging system for the knees and lower extremities. We also showcased  InReach and TALAS. Watch below to recap the show!



CurveBeam’s Top 5 Moments of 2016

Founded in 2009, the news of CurveBeam and its advanced, compact 3D imaging devices spread quickly among orthopedic and podiatric specialists. Just three years later, the CurveBeam pedCAT system cleared the FDA. Without losing any momentum, CurveBeam Europe LTD’s office was opened in London in 2013. Even with all of these notable accomplishments, 2016 shines as the most impressive year for CurveBeam thus far. From our President and CEO, Arun Singh, receiving a lifetime achievement award to our expansion into the Asian market, 2016 has been a year to remember.

Take a look at the top five most significant moments for CurveBeam in 2016.

  1. President and CEO Arun Singh presented the Lifetime Achievement Award

“In recognition and appreciation of [his] visionary contributions to the advancement of Cone Beam Computed Tomography,” the American Association of Dental Maxillofacial Radiographic Technicians presented Arun Singh with the Carl Gugino Lifetime lifetime-achievement-awardAchievement Award on October 7th. The award was presented to him by Mr. Jerry Peck, who owns dental imaging centers in the San Francisco area. In his speech, Mr. Peck described when Arun installed a Tomax system in one of his offices 27 years ago. He described how Arun worked overnight to create the software code Mr. Peck needed to run the calculations  for the measurements he was looking for.

“This is the type of person, how bright, smart, ingenious, he is. I mean, overnight, all of a sudden, the program is written,” Mr. Peck said.

Mr. Peck went on to describe how Arun cofounded Imaging Sciences and developed both the CommCAT and I-CAT, which were game changers for dental professionals.

“Today, you look at what is the most successful CBCT company in the world, and you built it Arun,” Mr. Peck said.

2. First Weight Bearing Users Meeting is Held

Focusing on the applications of the weight bearing cone beam CT, the first pedCAT Weight Bearing CT Scientific User’s Meeting was held at the 2016 Foot International in Berlin, Germany. “We can’t have non-weight bearing CTs and say anything about alignment – that’s over. What do we want to measure, and how do we know what we’re measuring represents reality?” said Dr. Charles Saltzman as he emphasized the importance of WBCT at the meeting.

3. First Podiatry School is Outfitted with pedCAT System

The Kent State University College of Podiatric Medicine became the first podiatry school to implement the revolutionary pedCAT cone beam CT imaging system. “Kent State University is proud to be the first facility in the Northeast Ohio region to provide this state-of-the-art imaging modality,” said Dr. Allan Boike, Dean and Professor of Foot and Ankle Surgery at KSUCPM. “The CurveBeam pedCAT will allow the college to improve the foot and ankle health of the community while providing the highest quality education for our students and research opportunities for our faculty and residents.”

Philadelphia is a city well known for its rich history, and CurveBeam is proud to be in its next chapter, as the company is now headquartered in this remarkable town. At the APMA “The National” meeting this summer, historical interpreters acting as Ben Franklin and Susan B. Anthony visited the CurveBeam booth to learn more about the revolutionary pedCAT technology.

5.CurveBeam Expands International Presence to Asia

Not only has CurveBeam expanded its domestic presence, the use of the technology worldwide is also growing. The pedCAT system received notable attention at the 2016 National Foot & Ankle Surgery Symposium in Qingdao, China, as CurveBeam’s Chinese partners presented the weight bearing CT technology to the audience of medical professionals.

It’s been quite a ride since our original team pioneered cone beam CT imaging technology for the podiatric specialty. As we gear up to expand into new orthopedic specialties, we could not be more excited for what 2017 will bring!

Comparison of Three Hindfoot Alignment Measurements: Radiographic Hindfoot Moment Arm, Radiographic Hindfoot Alignment Angle, and TALAS

Dr. Matthew Welck presented findings from a study overseen by Dr. Mark Myerson at the British Orthopedic Foot & Ankle Society (BOFAS) meeting in Bristol, England, in early November.

The study compared three hindfoot alignment measurements: radiographic hindfoot moment arm, radiographic hindfoot alignment angle, and TALAS. TALAS is a semi-automatic measurement based on anatomical landmarks on a weight bearing CT scan. TALAS was found to have the best intra-observer reliability.

As Dr. Welck explained, the TALAS technique measures offset of midline of whole foot, rather than just calcaneus. He presented an example of a patient with ‘neutral’ alignment to compare hindfoot alignment measurements. The first point was placed on the superior weight bearing portion of the talar dome. The calcaneus contact point was then placed on the lowest point of the calcaneus. The first metatarsal contact point was placed on the lowest point of the first metatarsal head. Similarly, the 5th metatarsal contact point was placed on the lowest point of the 5th metatarsal head. TALAS software provided a mapping of these contact points showing the axis, or the ’true’ hindfoot alignment.Next, Dr. Welck summarized the intra and inter observer reliability among the three measurements. As previously shown in the literature, Dr. Welck explained, there is good intraobserver reliability with the Saltzman hindfoot moment arm technique. Similarly, the hindfoot alignment angle has excellent intraobserver reliability. And there was excellent intra-observer reliability among investigators. Dr. Welck noted that while all three measurement techniques are reliable, the CT Ground Reactive Force Technique was nearly perfect.

CurveBeam’s pedCAT provides bilateral, weight bearing 3D CT imaging of the foot and ankle, greatly surpassing traditional imaging methods such as X-Ray and CT studies. CurveBeam’s technology also reduces the number of patient trips to the hospital, and exposes patients to less radiation. Because the 3D data generated by pedCAT is far more robust than could be interpreted by available software, CurveBeam engineers are collaborating with leading foot and ankle surgeons to develop a new measurement software – TALAS. TALAS, or Torque Ankle Lever Arm System, is a feature within pedCAT’s visualization application CubeVue.

The British Orthopaedic Foot & Ankle Society (BOFAS) is a society of orthopaedic surgeons who have a special interest in surgery of the foot and ankle. The Society works to encourage interest in foot and ankle surgery among orthopaedic surgeons and to encourage both basic science and clinical research in the field.

Value of 3D Reconstructions of CT Scans for Calcaneal Fracture Assessment

Operative fracture treatment of irregularly shaped bones, such as the calcaneus, scapula and scaphoid, demands high-quality images of the area in question for both classification of the fracture and planning of the procedure. However, since plain radiographs do not provide enough pertinent information to this end, computerized tomography (CT) has become the standard for providing the necessary images for treatment of these irregularly shaped bones.

Yet, in a study observing 2D CT scans, only 42% of the evaluators were able to correctly classify the fracture, necessitating the need for some sort of change. Three dimensional CT renderings were proposed to fix the low inter-rater agreement generated by the 2D scans.

The foot in the video above was scanned on a pedCAT weight bearing CT imaging system for the foot and ankle. The calcaneus was segmented using CurveBeam’s CubeVue visualization software. 

To evaluate the effectiveness of 3D CT scans, A standard set of CT secondary reformation scans were presented, followed by a questionnaire describing fracture anatomy and preoperative planning. Subsequently, 3D reconstructions were presented to the evaluates followed by the same questionnaire. After presentation of the 3D images, 49% of the evaluators changed their plan in regard to the approach and 29% in regard to the implants.

Five different data sets (four intra-articular and one extra-articular fractures) were presented to 57 evaluators. All groups, except that of surgeons with more than 20 years of experience, benefited from 3D CTs (Friedman test; P < .01). Inexperienced surgeons benefited more than experienced surgeons and complex fractures more than simple fractures. Specifically, regions of interest such as the middle facet and fractures extending into the calcaneo-cuboid joint were evaluated more precisely.

In regard to 3D CT scans, Böhmer1 described the topographic relationship between the fragments and the surrounding structures as useful for evaluating calcaneal fractures and for preoperative planning because the fractures can be seen from unusual perspectives. Likewise, Choplin2,3 posited 3D scans assist diagnosing foot deformities since the scans improve comprehension of the anatomy, particularly for especially complex fractures. For such complex fractures and anatomy, Pate5 evaluated 202 patients with complex musculoskeletal problems and found 3D CT particularly helpful. Others came to similar conclusions.

When comparing techniques for diagnosing foot deformities, Allon and Mears4 compared plain radiography, 2D CT, and 3D CT of 30 fractured calcanei and concluded that 3D CT improves preoperative planning and the choice of an adequate approach.

Overall, 3D CT scans provide insight previously unavailable through both 2D and plain radiography, which inexperienced surgeons tend to find more helpful in diagnosing and preoperative planning.
